Every year at this time I like to rank each team’s top prospects. My criteria is based upon both past performance and future potential to his parent team. This is my ranking of the 2012 Philadelphia Phillies Top Prospects. If you have any questions about my rankings, feel free to shoot me a message on twitter @Jaypers413

To qualify, a prospect must have fewer than 130 at-bats or 50 innings in MLB

Disclaimer – I did not attend any minor league games this year, nor do I claim to have any scouting experience. These lists are the product of my own research of statistics and online scouting reports.

With the 2011 minor league season complete we check in on the progress of each of the Philadelphia Phillies preseason Top 15 prospects as ranked by our prospect ranker J.P. Schwartz. The post season grading report was done by the publisher of Top Prospect Alert, not Mr. Schwartz, and reflects only the 2011 season and not future upside or downside of the individual prospect. Our 2012 preseason rankings will be published in the coming months.
